Succinate dehydrogenase flavoprotein subunit; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily.

Part of four member succinate dehydrogenase enzyme complex that forms a trimeric complex (trimer of tetramers); SdhA/B are the catalytic subcomplex and can exhibit succinate dehydrogenase activity in the absence of SdhC/D which are the membrane components and form cytochrome b556; SdhC binds ubiquinone; oxidizes succinate to fumarate while reducing ubiquinone to ubiquinol; the catalytic subunits are similar to fumarate reductase; Derived by automated computational analysis using gene prediction method: Protein Homology.

succinate--CoA ligase subunit beta; Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The beta subunit provides nucleotide specificity of the enzyme and binds the substrate succinate, while the binding sites for coenzyme A and phosphate are found in the alpha subunit.

succinate--CoA ligase subunit alpha; Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The alpha subunit of the enzyme binds the substrates coenzyme A and phosphate, while succinate binding and nucleotide specificity is provided by the beta subunit.

Fumarate hydratase; Catalyzes the reversible hydration of fumarate to (S)-malate. Belongs to the class-I fumarase family.

Aspartate ammonia-lyase; Involved in the TCA cycle. Catalyzes the stereospecific interconversion of fumarate to L-malate; Belongs to the class-II fumarase/aspartase family. Fumarase subfamily.

2-oxoglutarate dehydrogenase E1 component; Derived by automated computational analysis using gene prediction method: Protein Homology.

Succinate-semialdehyde dehydrogenase (NADP(+)); Catalyzes the formation of succinate from succinate semialdehyde; NADP dependent; Derived by automated computational analysis using gene prediction method: Protein Homology.

NAD-dependent succinate-semialdehyde dehydrogenase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the aldehyde dehydrogenase family.
